Iam sad to say that another
fine TINEXsinclair club has gone

out their last newsletter. They
decided to break up the group
for the same recsons any group
would dispand. We gill surely
miss them. Eight years ago Ba-

I have enclosed sy printed circuit board CAD

your wenbership groups and others. You be the
judge about hoo an advanced application can be
supported by the such saligned, but phoeniz-like
the TIMEXsinclair 2068.

Ghich sang deny exist. 811 1 can say is: “You
sean I can't do THIS?". THIS is impressive!

Qhen I sade the BOM BYPASS and sisnle HENORY
RANE SQITCHING public dosain, I included the
design of the QIDJUF PRIMGBY ADAPTOR and a pro-
posed standard for back-planes. This design
coapletes the data required te add back-planes
dand a1] the pouer that giges) to that inherently
SUPERIOR computer,

Even vithout B&NR SQITCHING or IBM BUSS
COMPATIBILITY, all existing harduare can be
sisply adapted to plug in. Heo hardoare, like
half aay decent parallel interfaces, can be nade
bith tuo edges. One edge plugs in for the
Binisus bus configuration -- the other for IBY
compatibility oith BAHR SQITCHING. The adaptor
is compatible uith existing hardoare, but nev
products vould better be consistent vith the neo
standard.

For those who have tight budgets (or fists),
the entire ingesteent to implesent a back-plane
is less than $90 for the sinisua configuration.
That for IBM compatibility will be someohat sore,
but the savings through the use of clone hoards
wakes that trivial.

The buss driver card is the only ites not
yet detailed. for the sinisus systes, ail the
design data has already been given.

The figures shoe both of the PRIBABY SDAPTOR.

The first personal computer

for under

The Sinclair ZX80.
A complete computer—
only $199. 95 plus $5.00 shipping.

Now, for just $199.95, you can get a
complete, powerful, full-function computer,
matching or surpassing other personal
computers costing several times more.

It’s the Sinclair ZX80. The computer that
“Personal Computer World” gave 5 stars
for ‘excellent value’

The ZX80 cuts away computer jargon
and mystique. It takes you straight into
BASIC, the most common, easy-to-use
computer language.

You simply take it out of the box, con-
nect it to your TY, and turnit on. Andif
you want, you can use an ordinary cassette
recorder to store programs. With the man-
ual in your hand, you'll be running programs
in an hour. Within a week, you'll be wnting
complex programs with confidence.

All for under $200.

Sophisticated design makes the
ZX80 easy to learn, easy to use.

We've packed the conventional computer
onto fewer, more powerful LSI chips—
including the Z80A microprocessor, the
faster version of the famous Z80. This
makes the ZX80 the world’s first truly port-
able computer (6%2” x 84%" x 1%" and a mere
12 oz.). The ZX80 also features a touch
sensitive, wipe-clean keyboard and a
32-character by 24-line display.

Yet, with all this power, the ZX80 is easy
to use, even for beginners.

Your course in computing.

The ZX80 comes complete with its own
128-page guide to computing. The manual
is perfect for both novice ang expert. For
every chapter of theory, thdre’s a chapter
of practice. So you learn by ¥omg—not just
by reading. It makes learningteasy, exciting
and enjoyable. -

You'll also receive a catalog packed With
items that can make your ZX80 even more
useful. Including 27 program cassettes, from
games and home budgeting for just $6.95,
to Sinclair's unique Computer Learning Lab
(a workbook, six cassettes with 100 lessons,
and two cassettes for storing programs).

ZX80’s advanced design features.
Sinclair's 4K integer BASIC has perfor-

mance features you'd expect only on much

larger and more expensive computers.

@ Unique ‘one touch’ entry. Key words
(RUN, PRINT, LIST, etc.) have their
own single-key entry to reduce typing
and save memory space.

$200.

@ Automatic
error detection.

A cursor identifies errors

immediatély to prevent entering

programs with faults.

@ Powerful text editing facilities.

@ Also programmable in machine code.

@ Excellent string handling capability —up
to 26 string variables of any length.

@ Graphics, with 22 standard symbols.

@ Built-in random number generator for
games and simulations.

Sinclair’s BASIC places no arbitrary re-
strictions on you—with many other flexible
features, such as variable names of any
length.

And the computer that can do soe much
for you now will do even more in the fu-
ture. Options will include expansion of 1K
user memory to 16K, a plug-in 8K floating-
point BASIC chip, applications software,
and other penpherals.

—,

Price includes TV and cassette connectors,
AC adaptor, and 128-page manual.

All you need to use your ZX80 is a standard TV
(color or black and white). The ZX80 comes complete
with connectors that easily hook up to the antenna
terminals of your TV. Also included is a connector for
a portable cassette recorder, if you choose to store
programs. (You use an ordinary blank cassette.)

computing—anc have fun learning.
